03 RXDI low end bog, top ends perfect!

[catfish96]

Hello! I have a 03 rxdi with a new SBT 951 and new impeller (13/19) and wear ring. The ski bogs and struggles to get to 25-30 then all the sudden jumps out of the water and runs 62 no problem. Setting the trim to center position helps the ski overcome the bog. Any ideas i know there are some pros out there! Thanks alot!

I had that exact same issue also. I would check the basics first. Fuel pressure, Air pressure, and rectifier. I replaced the rectifier and a new battery and the bog disappeared. Volts should be high 12's-low 13's when revving up. If that doesn't work I suggest inspecting the rave valve solenoid. The original should be green, I had a black one and it did not like it.
